Subsequently, the sample sets were cooled at different cooling rates – WQ (500 °C.s-1), AC (1 °C.s-1), and FC (0.08 °C.s-1).
The prepared samples were chemically etched with 10% HF or etchant 1.5ml HF + 2ml HNO3 + 10ml H2O.
The β-phase polyhedral grains are deformed, stretched in the hot rolling direction with an average length of 479 µm and a width of 159 µm (Fig. 1a).

This class of alloys are also widely applied in both automotive and aerospace industries, mainly as light constructional materials [1-2].
The last step was to provide the theoretical local density for each sample position, based on the macrosegregation profiles (which were experimentally determined by a Rigaku Rix 3100 X-Ray Fluorescence Spectrometer), by using the following equation [17]: (1 ) Results and discussion Fig. 1 shows the temperature data collected in the metal during the course of upward solidification of the Al-6wt%Cu1wt%Si (A) and the Al-6wt%Cu4wt%Si (B) alloys castings in the vertical unidirectional solidification setup.

The mixed phase Gs/TiO2 photocatalyst was obtained by mix GS and commercial TiO2 (98%, Loba Chemie, India) with the mol ratio of 1:1 and grind to homogeneity.
The mixed powder was calcined at 800 oC for 1 h under air atmosphere condition.

If the combined index (CI) value produced is less than 1 then the combination has a synergistic effect, equal to 1 is an additional effect only, and if more than 1 the combination has an antagonistic effect.

This paper demonstrates the usefulness and accuracy of deep-hole drilling (DHD) method [1] in a component predicted to contain a triaxial residual stress field.
The influence of different material models was also studied. 1.

In order to study the mechanical properties of improved multi-grid composite wall, the low-cycle reduplicative loading tests of 1/2 scale improved multi-grid composite wall were carried out.
The two models of composite walls were point contact multi-grid composite wall (DW-1) and light-steel skeleton multi-grid composite wall (DW-2).
